I have an L72 SS427 with a 2 row radiator and 7 blade clutch fan. It would run hot with 4 blades. As a matter of fact it does run hot with the 2 row radiator that was installed when I ordered the car. It has to run warm to burn the fuel with 11 to 1 compression. I was a Pontiac fan when I was a Kid and like the 69 Canadian 2+2.. Would like to find one and restore it. I like that split front grille. Too bad Morley couldn't restore His. NICK L72
